(Cyclohexylideneamino)oxyacetic acid and [chloro(phenyl)methyleneamino]oxyacetic acid: hydrogen-bonded R(8) dimers and aromatic - stacking interactions

Abstract: Molecules of (cyclohexylideneamino)oxyacetic acid, C₈H₁₃NO₃, (I), are linked into centrosymmetric dimers by pairs of O-HO hydrogen bonds [HO = 1.84 Å, OO = 2.6782 (12) Å and O-HO = 178°]. In [chloro(phenyl)methyleneamino]oxyacetic acid, C₉H₈ClNO₃, (II), the molecules are similarly linked into centrosymmetric dimers by pairs of O-HO hydrogen bonds [HO = 1.79 Å, OO = 2.6329 (17) Å and O-HO = 176°], and these dimers are weakly linked into chains by a single type of aromatic [bold pi] - stacking interaction.

Formula: C₉H₈ClNO₃ and C₈H₁₃NO₃
